A new roof installation means different things, depending on the state of the roof. There are several main components that make up the roof and may be replaced during a new installation. The following can help you determine what parts of your roof may need replaced.
Shingles and Underlayment
Every new roof installation begins with the removal of the old underlayment and shingles so they can be replaced with the new. In many cases, these are the only parts of the roof that are actually replaced. Once the old shingles and underlayment are removed, fresh underlayment, typically roofing felt, is installed and then the shingles are placed afterward.
Decking
The decking is the main plywood support structure of your roof. It can last for many decades and through several shingle replacements if it remains in good condition. Decking will need to be replaced if it suffers water damage, rot, or becomes punctured. You can have all of the decking replaced during your new roof installation, or just the damaged panels, depending on the type of damage.
Flashing
Flashing is another part of the roof that is typically replaced if the shingles are replaced. The flashing is the thin metal panels that seal the space where the shingles meet rooftop protuberances like chimneys and vents. Flashing may sometimes need to be replaced even if the rest of the roof is still in good condition.
Vents
Every pitched roof has a ridge vent, typically integrated into the ridge cap. There may also be additional vents caps on the roof. These don't necessarily need replacement when you have your new roof installed. Typically, they will only be replaced if they are damaged, missing, or if the old caps don't look nice on your new roof choice.
Fascia and Soffits
The eaves are made up of two parts -- the soffits on the underside and the fascia that faces outward. Both the fascia and soffit boards need replacing if they are damaged or suffering from rot. Many homeowners opt to have the eaves replaced with aluminum or vinyl materials when they have a new roof installed, since these materials are durable and won't rot.
Gutters
Gutters aren't typically replaced when the roof is replaced unless there is a problem with the current gutter system. Instead, your roofer will just remove the gutters and then replace them once the installation is complete.
